aosp 增加 home 键
查看具体键值
kernel/msm-4.9/include/uapi/linux/input-event-codes.h 和 frameworks/base/data/keyboards/Generic.kl 这个里面都可以看到 home 对应的是 172.
修改 dtsi
vim kernel/msm-4.9/arch/arm64/boot/dts/qcom/sq808-evk/qm215-qrd.dtsi
&soc {
gpio_keys {
home {
label = "home";
gpios = <&tlmm 127 0x1>;
linux,input-type = <1>;
linux,code = <172>;
debounce-interval = <15>;
linux,can-disable;
gpio-key,wakeup;
};
};
}设置开机唤醒
vim frameworks/base/core/java/android/view/KeyEvent.java
/** @hide */
public static final boolean isWakeKey(int keyCode) {
switch (keyCode) {
case KeyEvent.KEYCODE_BACK:
case KeyEvent.KEYCODE_MENU:
case KeyEvent.KEYCODE_WAKEUP:
case KeyEvent.KEYCODE_PAIRING:
case KeyEvent.KEYCODE_STEM_1:
case KeyEvent.KEYCODE_STEM_2:
case KeyEvent.KEYCODE_STEM_3:
case KeyEvent.KEYCODE_HOME:
return true;
}
return false;
